C#中用XmlDocument.SelectSingleNode读取XML时遇到问题,求救!!

Question

这样去获取试试：doc.DocumentElement.SelectSingleNode(...)

Answer 1

XmlNode node1 = doc.DocumentElement.SelectSingleNode("SOAP-ENV:Header/TransactionID"）这样选择节点试试！我很少加后面那个参数，不太明白呀！

Answer 2

回复m777:
不行,因为SOAP-ENV是有命名空间前缀的,不加命名空间提示错误:(

Answer 3

/// <summary>
/// 解析收到的Http响应，将body分解出来
/// </summary>
/// <param name="xmlMessage">收到的响应</param>
/// <param name="xmlMessageContent">Xml Body</param>
private void ParseContent(string xmlMessage,out string xmlMessageContent)
{
xmlMessageContent=xmlMessage.Substring(xmlMessage.IndexOf("<?")).Trim(); //Body //parse xml
byte[] byteSource=Encoding.GetEncoding("utf-8").GetBytes(xmlMessageContent);
MemoryStream ms =new MemoryStream(byteSource);
XmlTextReader reader=new XmlTextReader(ms);
string  parseLog=null;
while(!reader.EOF)
{
if(reader.MoveToContent()==XmlNodeType.Element)
{
        
parseLog+=("\r\n\t"+reader.Name+":"+ReadValue(reader));
                                           //处理关键字
}
else
{
reader.Read();
} }
Logs.writeLog(parseLog);

reader.Close();
ms.Close();


}

Answer 4

nsmgr.LookupNamespace("http://www.monternet.com/dsmp/schemas")

Answer 5

1、
nsmgr.AddNamespace("SOAP-ENV", "http://schemas.xmlsoap.org/soap/envelope");
nsmgr.AddNamespace("SOAP-ENC", "http://schemas.xmlsoap.org/soap/encoding");上面的命名空间与你XML文件全不一样，都在最后少了一个"/"
应该是：http://schemas.xmlsoap.org/soap/envelope/ 
        http://schemas.xmlsoap.org/soap/encoding/2、nsmgr.AddNamespace(String.Empty,"http://www.monternet.com/dsmp/schemas");
   不能使用String.Empty:
--------------
try:XmlNamespaceManager ns = new XmlNamespaceManager(doc.NameTable);
ns.AddNamespace("SOAP-ENV", "http://schemas.xmlsoap.org/soap/envelope/");
ns.AddNamespace("SOAP-ENC", "http://schemas.xmlsoap.org/soap/encoding/");
//注意下面的不同
ns.AddNamespace("xx","http://www.monternet.com/dsmp/schemas/");XmlNode node=doc.SelectSingleNode("SOAP-ENV:Envelope/SOAP-ENV:Header/xx:TransactionID",ns);
